True humor springs not more from the head than from the heart. It is not contempt; its essence is love. It issues not in laughter, but in still smiles, which lie far deeper.
Thomas CarlyleLet one who wants to move and convince others, first be convinced and moved themselves. If a person speaks with genuine earnestness the thoughts, the emotion and the actual condition of their own heart, others will listen because we all are knit together by the tie of sympathy.
